At this time, the processor on the air conditioner board 17 can update the device information 17B according to the operation state of the air conditioner 11.
　空調機１１が故障すると、空調機基板１７を空調機保守用基板１２と交換することで、空調機１１を修理する。この時、データ書換装置１３は、空調機基板１７から装置情報１７Ｂを読取り（Ｐ１）、装置情報１７Ｂに基づいてファームウェア１２Ａを空調機データ管理装置１４から取得し（Ｐ２）、装置情報１７Ｂに対応する装置情報１２Ｂおよびファームウェア１２Ａを空調機保守用基板１２に書込む（Ｐ３、Ｐ４）。 If the air conditioner 11 fails, the air conditioner 11 is repaired by replacing the air conditioner board 17 with the air conditioner maintenance board 12.

The air conditioner maintenance board 12 receives and stores the firmware 12A from the data rewriting device 13 (P4).
　これにより、空調機保守用基板１２は、電子基板に保持されていた装置情報１７Ｂに対応する装置情報１２Ｂを記憶し、装置情報１２Ｂに基づいて動作するファームウェア１２Ａを記憶することができる。このため、空調機１１が故障した場合においても、空調機１１に対応したファームウェア１２Ａを間違いなく空調機保守用基板１２に組み込むことが可能となり、保守作業の負担を軽減することが可能となるとともに、故障前の空調機１１に状態に整合させつつファームウェア１２Ａを実行させることができる。 Accordingly, the air conditioner maintenance board 12 can store the device information 12B corresponding to the device information 17B held on the electronic board, and can store the firmware 12A that operates based on the device information 12B. Therefore, even when the air conditioner 11 fails, the firmware 12A corresponding to the air conditioner 11 can be arbitrarily incorporated into the air conditioner maintenance board 12, and the maintenance work load can be reduced. In addition, the firmware 12A can be executed while the air conditioner 11 before the failure is matched with the state.
